Is it a good idea to invest £1500/month solely into S&P 500 over the long term?

While the S&P 500 is the gold standard of indexes, investing solely in investment vehicles that mirror the composition and performance of the fund may be too risky.

The reason is that the S&P 500 it has become too tech-heavy. The problem? Many financial experts think tech is in a dot-com bubble 2.0.

Here is perhaps a sound strategy to adopt:

Vanguard 500 Index Fund ETF

• 06/09: $388.72
• YTD Return: +13.25%
• Yield: 1.40%

Vanguard High Dividend Yield Index Fund ETF

• 06/09: $107.40
• YTD Return: +18.35%
• Yield: 2.82%

If you really want to invest in the S&P 500, you could always do a 75/25 split.
